Original: Characteristics and use methods of alkali swelling thickener in coatings

Compared with solvent-based coatings, coatings have the advantages of health, environmental protection and convenient construction, but their rheological characteristics are not as good as solvent-based coatings, such as delamination, agglomeration and other phenomena often occur when opening cans, and it is easy to splash, hang, etc.

Alkali swelling thickeners are used in coatings

Thickener is a kind of rheological additive commonly used in coatings, which plays a controlling role in the rheological properties of coatings, and the addition of thickeners can not only thicken the paint, but also give the paint excellent mechanical properties and physical and chemical stability, such as improving the thixotropy, anti-sagging and storage stability

Coatings without additive thickeners are difficult to meet storage, transportation and construction requirements

Main characteristics of alkali swelling thickener:

1 Without voc and APE

2 Effectively provides medium shear viscosity

3Operative splash resistance4 Provides excellent sagging and sinking resistance

5 Significantly improve the leveling of paint rolling or brush coating

How to use alkali swelling thickener:

One: The alkali swelling thickener can usually be added directly to the coating without dilution or pre-neutralization.

Two: Alkali soluble thickener needs to adjust the pH value with ammonia or AMP to achieve full activation.
